How To Check The Electric Narrow Gauge Locomotive Indicator

The battery electric locomotive is driven by the direct current provided by the battery through explosion-proof bolts, controllers, resistance boxes and other components to drive the motor. The battery electric locomotive indicator provides safety protection for the use of the electric locomotive. There will be a certain threat to safety. At this time, we must timely check the failure of the battery locomotive indicator light. The specific inspection method is as follows:

1. Observe that the controller power indicator (yellow) is off
Measure the battery locomotive whether there is a 48V power supply voltage between pin 12 and pin 10 of the socket A on the panel of the host. If not, check the 6A fuse, temperature control switch and related circuits. If so, the control board is broken and needs to be replaced.

2. The power indicator is on, and the start indicator (green) is off.

(1) Check if the 2 pin of controller B socket has 15V starting voltage, if not, the control board is broken; if it is, then measure the voltage of pin 1 of socket B, and there is no 15V on pin 1, then check the micro-motion in the photoelectric setter Switches and related circuits; if there is 15V on pin 1, check the control board.

(2) Check whether the power tube is broken down. If so, replace the power tube.

(3) Check whether the full-speed contactor is stuck, and if so, repair or replace the full-speed contactor
